Is it still blowing air and working otherwise?
There is an on-off button under the cover usually, but that only does exactly what the remote on-off button does.
If your feeling game, and are comfortable with live electricity, you can get to the controller board by removing a few screws and taking off the cover. You could check that the motor cable hasn’t come loose, but thats a real long shot. Could have a look for any burnt cables or components.

Be very careful, there is mains live electricity in there, if you aren’t sure, just replace it, the indoor units are relatively cheap.
Breakers can be faulty, so if you have a multimeter, test to be sure. Also, the live wires are right near the front, so cover them with tape and still treat it as if its live and be careful.
On mine (similar model, likely only cosmetically different), the live terminals are 3x screw terminals, and they are right next to the screw terminal to remove the last cover, so very easy to slip onto them.
Edit: I see you fixed it, all good :)
